Common Causes Of Poor Laptop Battery Life

1. Heat - placing the AC adaptor underneath the notebook during charging seriously degrades the battery over time. Similarly, leaving the notebook on top of a monitor, radiator or car window in direct sunshine are common causes of heat degradation (over a period of months).
2. Using the battery until it is flat. Lithium-Ion batteries tend to last longer if you avoid using them when they are nearly flat. Try to always charge them well before they become empty (ie as often as possible).
3. Leaving the Hp hstnn-db11 battery hp nc6000 battery in a fully discharged state. Typically this happens when you repeatedly switch the system on in order to use it for a few minutes longer after it has shut down due to a low battery, and then do not charge the battery for many months. The battery will then not charge due to a safety mechanism in the battery to prevent possible overheating and explosion which may result from charging a fully discharged battery.
4. Incorrect AC adaptor used. If the wrong AC adapter is used which has too low a voltage or current rating, the notebook may run on the mains but the battery may not charge. RM always label both the AC adaptor and the notebook with the same RM serial number.
5. Extended use. Lithium-Ion batteries are rated for 250-500 full charge/discharge cycles (depending on cell type used) at which point they will be at 50% capacity. After this they will rapidly deteriorate. All Lithium-Ion batteries have a finite life and will need to be replaced after prolonged use.
Tips for improving discharge times To increase the hp dv9700 laptop battery discharge time (maximum running time), try the following: 1. Set the Control Panel - Power profile to Max Battery and use timeouts to hibernate the system when not being used for more than ten minutes or so.
2. Set the power settings so that the screen and hard disk are disabled after five minutes of inactivity.
3. Reduce the screen brightness as much as you can.
4. Switch off the wireless card whenever you are not using it.
5. Disconnect any peripherals eg if you use a USB flash memory stick, copy any files you need and then unplug it. This can give an extra 20 minutes or so of use.
6. Do not connect PCMCIA cards (PC cards) unless you need to use them. Remove them when not needed.
7. Change the Control Panel - Alarm settings to their absolute minimum (eg 4%). This can gain an extra ten minutes of use (but the notebook may cut out suddenly if you have a degraded battery).
8. Do not access a CD more than required. If possible copy or install any software you might need from the CD onto the hard disk and then remove the CD.
